Brendyn Medina, a spokesperson for the Rapid City Police Department, told InsideEdition.com that only a few officers knew what Officer Allender, who's been with the department since 2014, had planned. But now that word has spread, they couldn't be happier.

“The Rapid City Police Department is bursting with excitement about the proposal," he said. "As soon as we learned the proposal had been captured on the in-car video, we knew we had to share it. This sort of nation-wide attention goes a long way to help the public recognize the human side of the public servants that protect our communities every day.

"Our agency, along with the Rapid City Fire Department, couldn’t be happier for Nick and Sarah.”

Medina added that Senior Officer Anderson proposed to his wife in a similar way a few years ago "so it was fitting that Anderson helps Officer Allender do the same."
